Agenda

Sustainable Heritage Network

What is the SHN?

The Sustainable Heritage Network (SHN) is a collaborative initiative and online platform that provides individuals, communities, and institutions with tools and online resources dedicated to the preservation, digitization, and management of cultural heritage and traditional knowledge.

TALM’s digitization needs:

• Digital preservation strategies aimed specifically at TALMs

• Hands-on, topic specific, short courses

• Online tutorials and resources

hands-on workshops

online resources

communities and workbenches

SHN WORKSHOPS

● Regional and national events.

● Hands-on, targeted training.

● Topics on digital preservation.

● Materials are shared through the SHN website.

ONLINE RESOURCES

Our resources can be browsed by:

● CATEGORIES

● COLLECTIONS

● MEDIA TYPE

● SHN WORKSHOP

● KEYWORDS

● SHN COMMUNITIES

SHN COMMUNITIES

Institutions or groups of people who share and manage content based on their cultural protocols.

SHN WORKBENCHES

Institutions offering digital services and training at physical locations.

• File Size and Quality

• File Formats• Digitizing Options

Digital Video Considerations

• Balance of Quality and Size• Consider your source!

• Adobe Premiere - match source• VHS quality

File Size and Quality

• The size of a video, in pixels.

1920x1080 - 1080p 1280x720 - 720p

720x576 720x480

352x480 320x240

Resolution

• The ratio of a video’s width to height.

4:3 - VHS formats16:9 - High Definition, widescreen

Aspect Ratio

• Frequency at which a device displays or captures the frames. (Frames per second)

digital video: 24, 25, 30 (and on)film: 16, 18, 24

VHS = 29.97

Frame Rate

• Bits per second• How much data is processed/captured in each frame• Higher bit rate = more data, higher quality, bigger

size • Balance Quality and Size

Bit Rate

• Video file is comprised of 2 things 1) Codec: Coder/decoder

Software that compresses/decompresses data

2) Container: Structure, how the file is stored (wrapper)

File Formats

• Well supported? • Open vs. proprietary? • Quality vs. size• Some common formats: AVI, MPEG-2, MP4,

Quicktime, WMV, MOV

File Formats, continued

• At WSU, we use...Master: AVI or MOVAccess: MP4

File Formats - Example

• Preservation Master• Access Copy• Web-ready derivative

File Formats - Master and Access

Standards

• Video standards - always changing/developing • FADGI

http://www.digitizationguidelines.gov/guidelines/

• Library of Congress Sustainable Formats http://www.

digitalpreservation.gov/formats/intro/intro.shtml

• Library of Congress, NARA, AMIA, Universities

• In house• Collaboration• Outsourcing

How to start digitizing?

• Size of collection• Format• Condition• Time and Resources• Budget

Factors to consider

• What format(s) is/are your content?• How much do you have?• What equipment do you need? Or are you thinking of

outsourcing? • How will you add information/metadata to the items?• How will you store the files that you create?• Are there any challenges or roadblocks to your project?

Discussion Questions - small groups

VHS Preservation and Digitization

Physical Preservation and Handling

Tape as an Archival Medium

● Magnetized particles on a polyester backing, adhered with a binder (very similar to audio cassettes!)

● Not good for long-term preservation (10-30 years)○ Specialized materials like LTO are different

● One option is to digitize○ And then migrate digital formats as needed

Preservation Concerns

● Sticky residue or powder on tape, which makes it difficult to play the tape

● Binder degradation (oxide flaking off the base)● Physical damage due to poor tape recorder

maintenance● Lack of equipment

Handling and Storage - Extending the Lifespan of VHS

● Manufacture/production quality● Care and Handling● Storage Conditions● Frequency of Access

Resources

● Association of Moving Image Archivists○ http://www.amianet.org/sites/all/files/WheelerVideo.pdf

● Conservation OnLine (American Institute for Conservation)○ http://cool.conservation-us.org/byauth/wheeler/wheeler2.html

VHS Digitization Equipment

1Playback

2Intermediary

hardware

3Digital capture

device

● What do you need?● What do you have?● What can you scrounge?● What is worth buying?

Playback devices

● Digitization unit, to convert the analogue output from playback equipment to a digital format

● Software to manage the digitization and capture● Software to edit and/or convert digital formats

Intermediary Hardware & Software

Types of Digitization Hardware

● A good computer○ Not a laptop

● Good processor● Enough RAM● Appropriate ports● Sufficient storage

Digital Capture Device

Capture Software

● WSU Libraries uses VirtualDub, Adobe Premiere, and Blackmagic Media Express○ Depends on hardware and project needs○ There are many others

● Most video capture cards include compatible software

Capture Software

Capture Software

Warnings!

● Digitizing, editing, and converting video takes a lot of processing power

● Any time you’re working with video, avoid doing anything else on that computer!

● Digitizing video generates large files● Work in a space which keeps your files visible, so they can be

easily deleted when done○ And use well-planned file naming and folder structure

Digitization Demonstration

Hands-on Practice!

General Workflow

● Detailed directions on hand out● Make sure everything is set up● Enter your filename and save location● Check audio and video connection● Record (~5 min)● Trim (if desired)

After Digitization: Editing

Editing Software

● Needed to edit video after capture○ Trim, insert, add cards, etc...

● Needed to convert between common file formats● If possible, find one piece of software that meets

all your needs

Professional Video Editing Software

● Adobe Premiere (Pro or Elements)● CyberLink PowerDirector● Corel VideoStudio● Final Cut Pro (for Mac)

Open Source Video Editing Software

● Shotcut● Lightworks● Avidemux

Editing Software

Editing and Processing

● Title Cards, Credits, Branding○ Watermarks

● Trimming excess/blank sections● Insert still images into videos● Adjusting audio or video levels

○ Colour correction

Editing and Processing

● Combining multiple videos● Splitting one video into several● Cropping or rotating● Exporting different types of files

Digitization - Project Planning and More

Digitization - the whole picture

• Project Planning Questions• Digital Preservation• Quality Control

• Document everything!

Project Planning - Should We Digitize?

• Scope and timeline• Outcomes and benefits• Permissions and copyright• How will you digitize?

Project Planning - Can We Digitize?

• Equipment and software• Physical Space• Staff• Digital storage needs• Metadata• Providing access

Project Management Tips

• Clear timeline• Digitization Logs or Tracking Sheets• Clear folder structure and file naming system• Staff training

Digital Preservation

• Long term storage and preservation of the digitized files

• Digital Preservation plan in place• Storage - 3-2-1 rule• File Integrity• File Access

Quality Control

• Two or more step process• Design for many stages of your workflow• Develop from beginning, include Quality

Control into your policies• Sample large projects

Quality Control for Video

• Storage and organization• Integrity • Adherence to decided technical specifications• Metadata• Visual and audio inspection - digital artifacts,

mistakes, dropped frames

• Sustainable Heritage Network• Preservation Self Assessment Program• Museum of Obsolete Media• Library of Congress• Connecting to Collections• Association of Moving Image Archivists• AVPreserve
